MATERIAL-HANDLING STATION.

Application filed .Tune 11,

This invention relates to a coaling station and is herein shown asapplied to a coaling station intended tor use tor coaling locomotives.It has for one object to provide in connection with such a station meansfor filling the storage bin from a track underlying the bin. Anotherobject is to provide means whereby the coal may be raised to the bin bya ktrack bucket passing beneath the track. Another object is theprovision ot means tor filling said bin by use ot a track bucket whichdumps into the bin alternately at opposite sides thereof. Other objectswill appear from time to time in the course et the specification andclaims.

I illustrate my invention moreor less diagrammatically in theaccompanying drawings, wherein:

Figure l is a vertical cross-section of a coaling station;

Figure 2 is a section on the line 2 2 of Figure l;

Figure 3 is a side elevation oi the bucket with parts in section;

Figure a is a section on the line 4l-l ot Figure 3.

Like parts are indicated by like symbols throughout the specication anddrawings.

A is a railroad track adapted to support a car A1 above a receivinghopper A2. The coal from the car is discharged into said track hopper.A3 indicates a loading tunnel formed by the side walls A4 and theinclined root portion A5. AG are doors through the walls A4, wherebymaterial may pass from the receiving hopper A2 to the loading tunnel.

B is a storage bin which may have the inclined bottom member or membersB1', supported upon any suitable fr inework B2. It will not be furtherdescribed7 since its details forni no part of the present invention.

Leading from the storage bin B is any suitable discharge chute or chutesC, ot which there may be any suitable number. By means ot these chutescoal is discharged into locomotive tenders or into any other suitablereceptacles.

D is a framework above the storage bin B, which may support the roof D1and any suitable hoisting mechanism not herein shown in detail, asforming no part of the present invention. D2 diagrammatically indicatesany suitable hoisting motor adapted to draw in or pay out upon the lineD3. D4

1927. Serial No. 198,037.

Df are any. suitable head sheaves and D5 D6 D* are pairs of idlersheaves, DS being a single idler beneath the track level. L

Referring to the bucket guiding means, F is an inner track member. Inthe form ot my device herein shown there 'are two such members, eachextending from the storage bin down along one side thereof to theiilling` hopper, said tracks being shown as coiitinuous, being joined bythe arcuate portion Fl which passes through the filling tunnel. F2 areouter track members, shown as terminating adjacent each mouth of theilling tunnel. The tracks F and F2 incline iiiwlardly as at F3, at eachside ot' the storage bin and are deformed thereabove, to provide dumpingmeans for the buckethereafter to be described. Each track F is providedwith a sharply inwardly inclined portion F4 ter minating in a bend F5which is connected bv the portion F6 with a terminal portion F7generally aligned with the track at The tracks F2 are outwardly archedas F2, as shown in Figure l. F10 is an arcuate track section positionedwithin the loading tunnel in opposition to the arcuate track Fl which atthat point is flattened as at F12.

The bucket employed includes a solid or iiXod bucket bottom G withbucket walls eX- tending from .opposite sides thereof' as at Gl G2 toJform two identical buckets having` open months G2 G1 facing in oppositedirections. The ends of the hoist line D2 are secured to the rigidcross-yokes which have at their ends guile rollers G6. The cross-yokesG5 are conne fted 'to the bucket by cable hails G7 which pivot as at GSto the sides ot the bucket in line with the fixed bottoni G. At thesides ot the buckets, in the walls G1 and G2, are positioned guiderollers G2 G10 and about said rollers are arcuate angle iron guides G11G12.

lt will be realized thatI whereas l have described and shown a practicaland operative device nevertheless many changes might be made in thesize, shape, number and disposition of parts without departing from thespirit of my invention. l theretore wish my description and drawings tobe taken as in a broad sense illustrative and diagrammatic rather thanas limiting ine to my specii'ic showing.

The use and operation ot my invention are as follows:

Goal or other material to be handled, is

` wardly in lil dumped into the receiving hopper, for cxample by releasefrom cars spotted on the track. Material passes by gravity :trom thehopper through the doors into the loading tunnel. The driving mechanismis then set in operation and the cable moves so to move the bucketthrough the loading tunnel, in either direction. The bucket havin@ anopen mouth at each end, it makes no d erence in which direction it pases through u ie tunnel, and the hoistingl mechanism is prei erablyactuated to move the bucket through the tunnel alternatelT7 in oppositedirections. Since a duplel bucket is used it is never necessary toreverse its diretion.` As the bucket passes through the tunnel the cableD3 guided by the bottom pair of id' D?. The guide rollers Gl; of thecross Y G5 are guided along 'the arcuate ti tion F1 and flattenedintermed tion F12. The bucket itself is heid against upward movement bythe arcua'"e upper tracks or angles F10. As the buck passes upwardly outof' the tunnel and alongy the vertical portion of the tracks F fw." F2the bail rollers G rollers G9 G10 on the bucketlguided between thetracks F i thus holding the bucket in vertical position. Vfhen thebucket reaches the er:-

panded track portion above desctibed, and assuming that the bucket istravelino upthe position shown in the guide roller GU rif1 the track F*until it reaches c ie bend 4its charge being` dumped into the storagebin. Upon reversal oi the hoisting; mecl` n'sin the bucket movesdownwardly to and through the loading` tunnel, passing); through iU inthe opposite direction.`

vWhereas in my preferred form i a bucket with a fined intermediatesomber, it will e realised that l. do wish to limit mjsel'fspecii'icaily to such a bucket or to ay fixed bottom in such a bucket,since under some circumstances i in i forms of my device a movablebucket` bottom may be employed.

lt will be observed that l am able to dispense with any reversal ot thedirection oi the bucket, and, in the form or" the fixed bottom., thebucket is tree from normally moving parts.

' I claim:
